Lady Sue likes to humiliate and punish slaves for little things. She made this old guy rue the day he was born when she punished him over something he had done a few months ago. She made him lick her soles and then trampled him. She did not care that he was old. She did not want to know how humiliating and degrading it was. She was concerned with her fun. That is all that mattered and that is what she did.
